Summary: (with fix) warning C4244: std::ostream::setw() with STLPort
Initial Comment:
vs2010 with STLPort.5.2.1 and Boost.1_52
XP SP3
error:
ql/math/array.hpp(634): warning C4244: 'argument' : conversion from 'stlpd_std::streamsize' to 'int', possible loss of data
ql/math/array.hpp(635): warning C4244: 'argument' : conversion from 'stlpd_std::streamsize' to 'int', possible loss of data
ql/math/matrix.hpp(584): warning C4244: 'argument' : conversion from 'stlpd_std::streamsize' to 'int', possible loss of data
The fix consists in providing a cast to int because required by STLPort std::ostream::setw() when compiling with vs2010 (and quite probably all others of versions of Microsoft compilers)
So the fixes are:
ql\math\array.hpp : lines 634, 635
#ifdef _STLPORT_VERSION
for (Size n=0; n<a.size()-1; ++n)
out << std::setw((int)width) << a[n] << "; ";
out << std::setw((int)width) << a.back();
#else
for (Size n=0; n<a.size()-1; ++n)
out << std::setw(width) << a[n] << "; ";
out << std::setw(width) << a.back();
#endif
ql\math\matrix.hpp : lines 584
#ifdef _STLPORT_VERSION
for (Size j=0; j<m.columns(); j++)
out << std::setw((int)width) << m[i][j] << " ";
#else
for (Size j=0; j<m.columns(); j++)
out << std::setw(width) << m[i][j] << " ";
#endif
